Question

An electric dipole is placed in an electric field increasing at the rate of Ξ» per unit distance along the x-axis. The dipole may undergo :

A
rotational motion only
B
rotational motion and translational motion along z-axis
C
rotational motion and translational motion along x-axis
D
only translational motion along x-axis
Solution
Verified by Toppr

Here the electric field will produce torque and force on the dipole.
The torque will give the rotational motion and force will give the translation motion of dipole along x axis.
